Assuming a declining correlation in yields as distance between pairs of orchards increases, yield variability in peach production may be reduced by increasing distances among orchards. As a measure of yield variability that avoids possible bias resulting from orchard-specific effects, a stochastic production function is estimated. Results support the assumption that a declining correlation between yields exists as distance increases. For every mile further apart, the correlation in yield declines 2.28%.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
